fuses or something else?
 

We have a 2001, x5, 4.4. Yesterday, after driving on the highway for a while we stopped at a rest area. When we got back on the road the speedometer, mpg guide quit working. Also, the dsc, brake and abs light all came on yellow. could this be a fuse problem or something else? The car is running fine, just can't tell how fast we are going and am concerned about the lights. Could this be a fuse problem or something else?
